Samsung is quite capable of making its own processors, the biggest endorsement of this came from the company itself when it decided to use its own Exynos chipset in the Galaxy S6 and the Galaxy S6 edge as opposed to the Snapdragon 810. There have been rumors that in the future Samsung will also develop its own GPUs or graphics processor, according to a new rumored roadmap Samsung is going to start using its own GPUs with Exynos chipsets by 2017 or 2018.
However before the company does that it's expected to employ Heterogeneous System Architecture (HSA) to its Exynos chipsets which will allow the CPU and GPU to be located on the same bus and let them share the same memory and tasks. In a nutshell this means that a handset with an HSA chip is going to provide improved overall performance and enhanced graphics performance. The rumored roadmap suggests that a Samsung Exynos SoC with HSA is going to arrive in a year or two with a Mali GPU and then by 2018 the GPU will be replaced by one Samsung has developed on its own in a newer Exynos chipset. So far Samsung has not confirmed anything regarding its plans to develop its own graphics processor so it would be best to take this with a pinch of salt for now.
